4 Claims.

This invention relates to smokers pipes.

It is one of the objects of the present invention to provide an improvedpipe which will function to minimize the nicotine and tobacco smell fromsmoke before smoke is inhaled.

In accordance with the principles of the present invention the pipe bowlis made in two parts. The upper part contains the fire bowl for tobaccoand the lower part contains smoke filtering material placed over a smokewell where the stem enters the pipe. The fire bowl consists of a tobaccoholder of metal or the like, perforated at the center to permit thedrawing of air through the tobacco. .A convex pan is placed under thebottom of the fire bowl and so arranged that when the two pipe parts areassembled the convex pan comes down on top of a mass of filter material.The bottom of the tobacco bowl is also made convex, the centercontaining the smoke drawing opening and the edges containing holesthrough which the tobacco drip that runs off of tobacco under heat maypass into the bottom pan where the drip is retained.

The pipe will last indefinitely since there is nothing readily to wearout nor to burn out, except, perhaps, the filter material, which mayreadily be replaced. Should the whole pipe seem to have accumulated atobacco or smoke taste it may be taken apart and washed without injuryto the parts, thus producing the effect of a new, fresh pipe.

The pipe body may be made of any desired material such as, for instance,wood, plastic or other pipe materials. Also, the inner part of the pipe,such as the fire bowl and the convex pan above the filter, may be madeof any desired materials.

The attainment of the above and further ob jects of the presentinvention will be apparent from the following specification taken inconjunction with the accompanying drawing forming a part thereof.

In the drawing:

Figure 1 is a longitudinal sectional view of a pipe embodying thepresent invention;

Figure 2 is a section taken alon the line of Figure 1;

Figure 3 is a section of Figure 1;

Figure 4 is a fragmentary prospective view of the tobacco receptacle orburner of the pipe of Figure 1; and

Figure 5 is a perspective view of the drip pan of the pipe of Figure 1.

Referring now more particularly to the drawtaken along the line 33 ing,the pipe 1 consists of the usual stem I2, which may be in one or moreparts, and a twopiece bowl 3. The two-piece bowl consists of an uppersection 4 and a lower section 5 which, in this instance, is integralwith a part of the stem 12. This much of the pipe may be of any other orstandard construction.

The upper section 4 of the pipe bowl has a container or fire bowl Iremovably fitted snugly thereinto. The container may be of a thinsection of metal or of any other desired material. The container hasholes 89 formed at the bottom periphery thereof and has an upwardlyconvex bottom ID with a central hole ll therein. The bottom of thecontainer 1 is spaced from the inside of the bowl section 4 by a spaceI3. The bottom bowl section 5 has a drip pan l5 removably insertedtherein but fitting snugly in place. The drip pan has an upwardly convexbottom H3 at the top of which there are one or moreholes ll--ll. Belowthe drip pan I5 is a space I8 filled with a replaceable smoke filter [9,below and at the center of which is a smoke and air chamber 20, whichchamber 20 communicates with the usual duct 21 in the pipe stem.

In smoking the pipe the tobacco is placed in the container i and ignitedin the usual manner. Any moisture that may condense, or tobacco dripthat may be formed, will naturally gravitate to the bottom of thecontainer 1 and, because of the upwardly concave shape of the bottom, itwill fiow out of the container at the holes 9 therein, thus droppinginto the pan [5. When suction is applied to the pipe stem a current isdrawn through the holes 8 in the container 1, and the holes H in the panl5, thence it fiows through the smoke filter Hi to chamber 20 and to thepassageway 2 I.

It is to be noted that there-is an appreciable space I4 between the panl5 and the bottom of the container 1. As a result of this space thecondensate in the pan I5 is not subjected to appreciable heat andtherefore does not tend to volatilize to any appreciable extent. If anysuch volatilization were to take place the vapors would necessarily fillthe space M above the pan and then would be drawn .through the stem 21during the smoking action and thereby impart a bitter and objectionabletaste and smell to the smoke. The pipe may easily be taken apart forcleaning.

The lower section 5 of the pipe is provided with a central vent 22 whichis of very small diameter. This allows the smoker to draw in a certainamount of air which is mixed with the smoke before it gets to the mouthof the smoker, thereby reducing the temperature of the smoke. Anotherpurpose of this vent is that a y smoke that is accidently blown backinto the pipe by the smoker can be expelled through the vent withouthaving to pass through the filter I8 and the mass of tobacco in thebowl. If desired this vent may be omitted.

The pipe proper may be made of any materials now used for pipes, suchas, for instance, wood, plastic, clay, or the like. Furthermore, thefire bowl I and the convex pan l5 may also be made of any desiredmaterial. It is thus apparent that the pipe of the present invention issimple and economical of construction, certain and reliable in itsaction and afiords the benefits above set forth.

In compliance with the requirements of the patent statutes I have hereshown and described a preferred embodiment of my invention. It is,however, to be understood that the inventim is not limited to theprecise construction here shown, the same being merely illustrative ofthe principles of the invention. What I consider new and desire tosecure by Letters Patent is:

1. A tobacco pipe including a bowl, a tobacco container in the upper endof the bowl, a pan below the container for catching and retainingmoisture formed in the container and means forming a suction passagewaybelow the pan, said pan and said container having openings therethroughfor applying suction therethrough, the pan and the bottom of thecontainer being both upwardly concave as viewed from below, and theopening through the pan being in the top thereof, the lower periphery ofthe pan being imperforate to hold the moisture collected in the pan, theopenings in the container being some at the lower outer periphery of theconcave bottom and some at a level above the lower outer periphery ofthe concave bottom the pan being spaced from the bottom of the containerto be substantially outside of the zone of combustion in the containerby burning tobacco, whereby the moisture that collects in the pan issubjected. to a minimum of volatilization, and a mass of filteringmaterial filling the pocket formed by the underside of the upwardlyconcave pan.

2. A smokers pipe including a bowl, a generally cup=-shaped tobaccoholder in the bowl, the bottom of the holder being upwardly concave asviewed from below for guiding moisture that is formed in the pipe to.the periphery of the container, said holder having openings in thebottom periphery for permitting the outflow of such moisture, and havingat least one smoke-flow opening above said first mentioned openings, adrip pan in the bowl below the tobacco holder, said pan being alsoupwardly concave as viewed from below and imperiorate around its outerperiphery to collect and hold the moisture dripping from the tobaccoholder, said pan having a suction opening therethrough in the upper partthereof, and means forming a suction passageway below the pan.

3. A smokers pipe including a bowl, a substantially cup-shaped tobaccoholder in the bowl,

the bottom of the holder being upwardly concave as viewed from below forguiding moisture that is formed in the pipe to the periphery of thecontainer, said holder having openings in the bottom periphery forpermitting the outflow of such moisture, the holder fitting snuglywithin the bowl for the major portion of the area of the side of theholder but being of a slightly less outside diameter at the bottomthereof than the adjacent inside diameter of the bowl to leave a spacebetween the bowl and the side of the holder at the lower portion of theholder, the lower portion of the side of the holder having perforationstherethrough for the passage of smoke from the holder into said space, adrip pan in the bowl below the tobacco holder, said pan being alsoupwardly concave as Viewed from below and imperforate around its outerperiphery to collect and hold the moisture dripping from the tobaccoholder, said pan having a suction opening therethrough the upper partthereof, a mass of filtering material filling the pocket formed by theunderside of the upwardly concave pan and extending across the suctionopening therethrough, and means forming an air suction passageway belowthe pan.

4. A tobacco pipe including a bowl, a removable tobacco container in thebowl and extending up to the top of the bowl, the container having anupwardly curved bottom so that moisture forming therein will be guidedto the periphery thereof, the periphery of the bottom of the containerbeing perforated to permit moisture therethrough, the lower portion ofthe side of the container that extends upwardly from the periphery ofthe bottom being spaced from the inner surface of the bowl to leave aspace between the inner surface of the bowl and the lower portion of theupwardly extending side of the container and being perforated above thebottom or" the container so that some smoke being, drawn through thepipe will pass through the container through the periphery thereof andabove the first mentioned moisture passing perforations, an upwardlycurved pan below the. container for catching and holding condensedmoisture,

said pan having an opening thereth-rough, a smoke filter chamber belowthe pan, and a suc tion passageway leading to said chamber.
